MAX5141EUA+

MAXIM INTEGRATED PRODUCTS  MAX5141EUA+  数模转换器, 电压输出, 14 bit, 串行, 4.5V 至 5.5V, µMAX, 8 引脚

The is a +5V, serial input, voltage output, 14bit DAC in 8 pin µMAX package. It offers full 14bit performance with less than 1LSB integral linearity error and less than 1LSB differential linearity error thus ensuring monotonic performance. The unbuffered DAC output results a low supply current of 120µA and a low offset error of 2LSBs. The DAC output range is 0V to VREF. A 16bit serial word is used to load data into the DAC latch. The 25MHz, 3-wire serial interface is compatible with SPI/QSPI/MICROWIRE and can interface directly with opto couplers for applications requiring isolation. A power-on reset circuit clears the DAC output to code 0 when power is initially applied. A logic low on CLR asynchronously clears the DAC output to code 0 independent of the serial interface. Typical applications include high resolution and gain adjustment, automated test equipment and data acquisition systems.
